Ion-exchange resin and carbon against limescale
The capsule sits inside the humidifier filter cartridge. Purolite ion-exchange resin binds the lime in the water and carbon granules help inhibit bacteria, so limescale does not corrode the inside of the Beam mini. When a capsule reaches the end of its life, only the capsule is replaced and the cartridge stays. With two capsules in the pack, the next change is covered.
